//! This module contains the various end point definitions for stellar's horizon
//! API server. An endpoint is a struct that implements the `IntoRequest`, and `TryFromUri`
//! traits.  Endpoints can be given to a client for fetching into a response.
//!
//! # Example
//! ```
//! use stellar_client::sync::Client;
//! use stellar_client::endpoint::transaction;
//!
//! // Instantiate a client connected to the horizon test network
//! let client = Client::horizon_test().unwrap();
//!
//! // Create a struct that represents the "all" transactions endpoint
//! let txns = transaction::All::default();
//!
//! // Give the endpoint to the client and receive back a `Records` struct
//! // that provides the resulting set of transactions
//! let all_txns = client.request(txns).unwrap();
//! ```
